why dont we all do it if stops us getting caught by speed cameras?

Actually it doesn't work at all. I was watching a show on it a few days ago where they tested all the plate hiders and radar jammers on the market.

The only one that worked was a cover that cut off the last 2 numbers. Which means if a cop saw you driving down the road they'd see it and pull you over since it's illegal.

Saw the show too. None of that stuff works and is illegal anyway. My wife got pulled over with the diffusion cover over her plate and had to remove it on the spot.

If you live in America then WHAT speed cameras? There is only one and thats in the Phoenix, AZ area, and even that has lame warnings telling you that you are approaching a photo enforced area...

They don't work. There have been a bunch of tests done on them, and Mythbusters even did a segment on them where they tested a ton of them using an actual traffic camera and proved that they don't work.

You mean why don't we all illegally deceive the police and drive dangerously fast?

Why don't we all lie about having cancer so we can legally smoke pot with a prescription?

b ecause it doesn't always work.
